Is it possible to add the "continue reading " button from the "grid" layout also to "grid layout with sidebar" ? Please.
It is possible with custom code, you must use a child theme and create a new grid-article.php file with the custom button.
Below i attached the child theme with the customization, if you need more customization i recommend you to copy and paste the file you need (from reco theme) and paste into reco-child folder.
Just upload the zip into your themes section and activate it (Reco theme must be installed to in order to work).
Attached files: reco-child-custom-reading.zip
